Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ALSA: usx2y: Use snd_card_free_when_closed() at disconnection<br />
<br />
The USB disconnect callback is supposed to be short and not too-long<br />
waiting. OTOH, the current code uses snd_card_free() at<br />
disconnection, but this waits for the close of all used fds, hence it<br />
can take long. It eventually blocks the upper layer USB ioctls, which<br />
may trigger a soft lockup.<br />
<br />
An easy workaround is to replace snd_card_free() with<br />
snd_card_free_when_closed(). This variant returns immediately while<br />
the release of resources is done asynchronously by the card device<br />
release at the last close.
